Linking mesoscale landscape heterogeneity and biodiversity: gardens and tree cover significantly modify flower-visiting beetle communities [PDF]

open access: yes, 2019
Context Maintaining biodiversity in multifunction landscapes is a significant challenge. Planning for the impacts of change requires knowledge of how species respond to landscape heterogeneity. Some insect groups are known to respond to heterogeneity at

Landscape variation in soil carbon stocks and respiration in an Arctic tundra ecosystem, west Greenland

open access: yesArctic, Antarctic, and Alpine Research, 2018
The magnitude and acceleration of carbon dioxide emissions from warming Arctic tundra soil is an important part of the Region’s influence on the Earth’s climate system.

The Effects of Urban Sprawl on Birds at Multiple Levels of Biological Organization

open access: yesEcology and Society, 2004
Urban sprawl affects the environment in myriad ways and at multiple levels of biological organization. In this paper I explore the effects of sprawl on native bird communities by comparing the occurrence of birds along gradients of urban land use in ...

Deforestation, leakage and avoided deforestation policies: a spatial analysis [PDF]

open access: yes, 2015
This paper analyses the impact of several avoided deforestation policies within a patchy forested landscape. Central is the idea that deforestation choices in one area influence deforestation decisions in nearby patches.

Landscape heterogeneity, connectivity, and critical landscapes for conservation

open access: yesDiversity and Distributions, 1999
SummaryLandscapes are diverse in the frequencies and distributions of habitat types. Does landscape heterogeneity, as a higher order (i.e. at a pheno‐ menological scale coarser than that of organisms) of diversity, allow greater connectivity; does higher order diversity change higher order functions?

Biodiversity as spatial insurance in heterogeneous landscapes [PDF]

open access: yesProceedings of the National Academy of Sciences, 2003
The potential consequences of biodiversity loss for ecosystem functioning and services at local scales have received considerable attention during the last decade, but little is known about how biodiversity affects ecosystem processes and stability at larger spatial scales.

Examination of the seepage face boundary condition in subsurface and coupled surface/subsurface hydrological models [PDF]

open access: yes, 2017
A seepage face is a nonlinear dynamic boundary that strongly affects pressure head distributions, water table fluctuations, and flow patterns. Its handling in hydrological models, especially under complex conditions such as heterogeneity and coupled ...

Female Greater Prairie‐Chicken response to energy development and rangeland management

open access: yesEcosphere, 2019
Wildlife habitat use is the result of behaviors that occur at multiple spatial and temporal scales. The interactions between these behaviors can often result in complex patterns of selection that can make it challenging to select the most appropriate ...

Predictors of brown bear predation events on livestock in the Romanian Carpathians

open access: yesConservation Science and Practice, 2023
Livestock depredation by brown bears is one of the main source of human–wildlife conflict in rural Eastern Europe. Thus, identifying environmental and anthropogenic drivers of human–bear conflict, and developing spatial predictions for predation ...

Organoids in pediatric cancer research

open access: yesFEBS Letters, EarlyView.
Organoid technology has revolutionized cancer research, yet its application in pediatric oncology remains limited. Recent advances have enabled the development of pediatric tumor organoids, offering new insights into disease biology, treatment response, and interactions with the tumor microenvironment.
